Lose yourself in movies and music

Looking to take your home theater to the next level? Match Yamaha's AVENTAGE RX-A870 to a 4K Blu-ray player and you can enjoy the same video content in crystal-clear Ultra HD on up to two compatible displays — perfect if you have both a TV and a video projector. Dolby Atmos and DTS:X bring movie soundtracks to life with incredible realism.

Music lovers will appreciate this receiver's ability to play different high-resolution audio formats through the front-panel USB port or from a networked computer. And if you're into vinyl, a phono input provides an easy connection for your turntable.

The AVENTAGE difference

For their AVENTAGE-series receivers, Yamaha uses custom-designed parts with anti-resonance technology to reduce distortion caused by vibration. A rigid H-shaped frame adds stability to cut out chassis vibration almost completely. A specially designed fifth foot at the center of the receiver's base dampens internal and external vibrations, and an aluminum front panel further reduces resonance to maximize sound quality.

The RX-A870's meticulous construction, symmetrical amplifier layout, and low-jitter digital circuitry all work together to give you accurate sound with precise stereo imaging and a wide, natural soundstage.

Loads of wireless listening options

Built-in support for streaming services like Spotify®, TIDAL, and Pandora® lets you play and control your favorite music directly through the receiver. Apple® AirPlay® lets you stream from a compatible iOS® device, and Bluetooth adds even more streaming flexibility. You can even stream audio from the receiver to a set of Bluetooth headphones — great for late-night listening.

MusicCast lets you choose how to listen

Setting up a whole home wireless music system has never been easier. This receiver's built-in MusicCast technology lets you add audio playback in up to nine additional rooms with compatible Yamaha wireless speakers and sound bars.

MusicCast lets you stream music from your personal collection, internet radio, and streaming services. You can also play Bluetooth sources, sound from your TV, and even CDs and vinyl. The free MusicCast Controller app makes it easy to access your music and control what you have playing in different rooms.

Flexible speaker connections for a custom sound system

The RX-A870 has outputs for nine speakers, giving you a few different configuration options. You can set up a standard 7.2-channel surround sound system or a 5.1.2 Dolby Atmos system, and use the extra two speaker outputs to power a pair of speakers in a second room. That way, you can enjoy stereo music in Zone 2 while others watch TV in the main room.

When Zone 2 is powered on, Yamaha's Intelligent Amp Assign feature automatically redirects the power for the two surround back channels — or the front height channels, depending on your configuration — to your stereo setup in Zone 2, giving you five-channel surround sound in the living room.

If you're happy with a simple 5.2-channel surround sound system, you can also use one of the extra sets of speaker outputs to bi-amp your front speakers for more powerful sound.

Product Research

Audio Section

Aventage Series: The Aventage line of Yamaha AV receivers is
based on the audio design concept of providing a massive, full-bodied sound for
movie sound effects and the accurate reproduction of music sources. By expertly
harmonizing traditional and advanced technologies, every factor that affects
sound quality, from materials & parts construction to circuitry layout,
vibration damping, and "fine-tuning" the sound, is handled with no other thought
than to achieve the best possible audio quality. As a result, every Aventage
receiver has the ability to reproduce the most subtle details of high-definition
sound, so that listeners can enjoy a truly high-class sound studio experience at
home.

High Drive Amp Technology: A fully discrete power
amplifier helps maximize sound and minimize distortion of the receiver. The
Yamaha RX-A870 AV Receiver is equipped with a 7-channel amplifier rated at
100 watts (into 8-ohms, at 20-20kHz, with 0.06% THD, driving 2 channels)
which provides high dynamic power with low-impedance drive capability.

High Purity Pre-Amplification: The Yamaha RX-A870 uses
high quality, audio-grade Burr-Brown 192kHz/24-bit digital-to-analog
converters for all channels to maximize sound quality. The AV receiver also
utilizes low-jitter PLL circuitry to help optimize sound imaging. The result
is a more dynamic sound with greater detail and less distortion.

Independent Power Supplies: Independent power supplies
are used for the receiver's analog and digital circuitry to prevent digital
noise from affecting analog circuitry. These power supplies are highly
efficient and result in less power consumption in standby mode.

Aluminum Front-Panel: The aluminum front-panel is used
to effectively shield sensitive circuitry from external noise and electronic
energy generated by dimmer switches, fluorescent lighting, video monitors
and so on. This ensures optimum sonic performance in the widest range of
installation environments.

Anti-Resonance Technology: The Anti-Resonance
Technology (A.R.T) Wedge is a fifth foot in the center of the unit. It
dampens vibrations from the power transformer, power transistors and heat
sinks, as well as vibrations that might be caused by the sound from the
speakers.

Advanced Design Feet: The feet of the receiver feature a newly
designed, high-density structure which utilizes two different kinds of
interior ribs (straight and curved) to enhance strength and damping
performance. Installation stability is improved and chassis resonance is
dispersed, effectively eliminating external vibration. The low-range
response is enhanced, while resonance peaks in the mid- and high-range are
reduced, providing dynamic sound and accurate reproduction.

Intelligent Amplifier Assignment: Intelligent Amp Assignment
automatically assigns amplifier channels of the Yamaha AV receiver to certain
speakers depending on what speaker layout has been selected and what content is
being played back. You can connect up to nine speakers to the AV receiver and it
will determine which seven speakers need amplification. You can choose from a
variety of amplifier speaker layout configurations.

7.1/5.1.2 Surround: In this configuration, up to nine
speakers (Front L/R, Front Presence L/R, Center, Surround L/R, & Surround
Back L/R) can be connected to the AV receiver. When Cinema DSP HD3 is on or a
Dolby Atmos soundtrack is being played, the two Front Presence or Dolby
Atmos speakers will be powered and not the two Surround Back speakers. When
Cinema DSP HD3 is off or Dolby Atmos is not playing, this situation is
reversed and the Front Presence or Dolby Atmos speakers turn off while the
Surround Back speakers are powered. Bi-amp and Zone 2 speakers are not
available in this mode.

Dolby Atmos + Zone 2: In this setup, you can hook up a
5.1.2ch Dolby Atmos speaker system in the main room and a pair of speakers
in Zone 2 to the receiver. When Zone 2 is off, all seven channels of your
Dolby Atmos speaker system will be powered. However, when Zone 2 is turned
on, power to the Front Height, Overhead, or Dolby Atmos speakers will be cut
off and directed to the pair of speakers in Zone; limiting you to only 5.1ch
surround in the main room. Bi-amp & Surround Back speakers are not available
in this setup.

7ch + Zone 2: In this configuration, up to nine
speakers (Front L/R, Center, Surround L/R, Surround Back L/R, and Zone 2)
can be connected to the AV receiver. When Zone 2 is off, all seven channels
will be used in the Main Zone. However, when Zone 2 is on, power to the two
surround back channels will be directed to the two speakers in Zone 2 and
the Main Zone will receive five channels of power. The same or different
analog input sources/volume settings can be applied to both zones. Bi-amp,
Front Presence, & Dolby Atmos speakers are not available in this mode.

5ch Bi-Amp: Up to five speakers (Front L/R, Center, &
Surround L/R) can be connected to the AV receiver. The Surround Back
amplifier channels of the AV receiver are reassigned to bi-amp the front
speakers. A bi-amplification connection uses two amplifiers for one speaker.
One amplifier is connected to the woofer section of a loudspeaker while the
other is connected to the combined midrange and tweeter section. With this
arrangement each amplifier operates over a limited frequency range, making
its job easier. Zone 2, Front Presence, & Dolby Atmos speakers are not
available in this mode.

YPAO Sound Optimization: This unit employs the YPAO (Yamaha
Parametric Acoustic Optimizer), which automatically adjusts the output of the
speakers based on placement, performance, and the room's acoustic
characteristics. Yamaha's YPAO system uses a small microphone and sophisticated
equalization to automatically set the best sound for any room, no matter where
the speakers are. First it checks the speaker connections and phase of each
speaker. Then it sends out tones which are captured by the microphone to analyze
the room acoustics and sets a variety of parameters; such as the speaker size,
the distance of the speakers, and even the volume level; until it achieves the
best sound conditions for your room.

R.S.C. (Reflected Sound Control) Multipoint: The
receiver employs R.S.C. (Reflected Sound Control) to correct early
reflections for studio-quality surround sound. Up to 8 listening position
measurements are taken to optimize the surround effect for a broad area (you
can store up to two speaker patterns).

EQ: 6Choose between 3 YPAO EQ modes -
Natural (adjusts all speakers to a natural sound; useful when the flat
setting sounds too bright), Flat (use when all the speakers in the system
have similar sound characteristics), or Front (EQs the center and rear
speakers to sound like the front; useful when your front speakers are better
than the others in the system)

DSP Effect Normalization: In addition, the receiver's
YPAO Sound Optimization provides DSP Effect Normalization, which varies the
Cinema DSP parameters according to the reflected sounds in the room.

YPAO Volume: Human ears have less sensitivity to high
and low frequencies, especially at lower volumes. YPAO Volume applies
loudness EQ correction to automatically adjust high and low frequency levels
as volume changes. Using the YPAO measurement results, EQ correction is
optimized to your system settings and listening environment.

Note: You can also choose to manually adjust the AV
receiver's speaker, crossover, & EQ settings.

Dolby Atmos: The Yamaha AV receiver will enhance
properly designed systems with
Dolby Atmos where sound comes alive from all directions, including
overhead, to fill the home theater with astonishing clarity, power, detail
and depth. The RX-A870 has the processing power to run a more enveloping
5.1.2ch Dolby Atmos layout utilizing front-height, ceiling mounted, or Dolby
Atmos-enabled speakers (sold separately). A 5.1.2 speaker configuration is
based upon a traditional 5.1 speaker layout complemented by two Front
Height, Overhead, or Dolby Atmos-enabled speakers.

DTS:X:
DTS:X is the next generation object-based, multi-dimensional audio
technology from DTS. Unbound from channels, DTS:X conveys the fluid movement
of sound to create an incredibly rich, realistic and immersive soundscape -
in front of, behind, beside and above the audience - more accurately than
ever before. DTS:X offers the ability to automatically adapt the audio to
the speaker layout that best fits your space.

Dolby Surround:
Dolby Surround offers an enhanced cinema experience to your 2ch and
multichannel movie soundtracks using your existing 5.1ch, 7.1ch or Dolby
Atmos speaker setup. Dolby Surround enhances audio definition by improving
the spatial dimension and overall audio definition of movie soundtracks. It
does this by using four distinct surround zones that provide greater control
over the exact placement of each detail in a movie sound track, so audio can
be matched more accurately to the video on screen; this means more depth and
greater realism for your movies. As a result, individual sounds are clearer
and more distinct. It also improves the surround sound experience across the
entire theater by widening the listening "sweet spot".

Neural:X: DTS:X incorporates Neural:X, the latest
spatial remapping technology from DTS, which provides a fully immersive
output for all types of source content; this includes DTS bitstreams and
non-encoded (PCM) data. Neural:X delivers a thrilling sense of immersive
sound to your speaker layout regardless of the original source format.

DTS Neo:6: DTS Neo:6 is an advanced matrix decoder that
takes any two-channel source (including television broadcasts, CDs and DVDs)
and expands it into five or six channels. It also provides separate,
optimized modes for stereo music materials and matrix surround motion
picture soundtracks. DTS Neo:6 brings you a more revealing sound from
ordinary stereo and a more expansive home cinema experience.

Cinema DSP 3D: The actually measured soundfield data in
recorded soundtracks contain the information of the height of the sound images.
Cinema DSP 3D mode achieves the reproduction of the accurate height of these
sound images so that it can create the accurate and intensive stereoscopic
soundfield in your listening room. Yamaha Cinema DSP 3D
lets you enjoy your movies and music even more in your home; regardless if you
are using 5.1 speaker setup, only have a two-channel speaker system, or
listening through headphones.

Virtual Presence Speaker (VPS): With the power of
Cinema DSP 3D technology and the Virtual Presence Speaker (VPS) mode, the
receiver virtually reproduces the height of the 3D soundfield without
actually having front presence speakers. The Virtual Presence Speaker
function makes full use of center and surround speakers to create audible
information from where presence (height) speakers are normally installed.

Virtual Surround Back Speaker (VSBS): This receiver
also features a Virtual Surround Back Speaker function. Even without using
surround back speakers, you can experience more natural, lifelike sound from
behind you without physical speakers being installed in the surround back
area of the listening environment.

Virtual Cinema DSP: Virtual Cinema DSP is an algorithm
that allows you to enjoy DSP soundfield surround effects while using a
minimal two-speaker system. Virtual Cinema DSP lets you enjoy the effects of
Cinema DSP surround sound without using surround speakers (handy for use in
custom installations where some rooms don't have surround speakers). It can
be used with the front/center speakers or even with just the two front left
and right speakers. This unit will switch to virtual Cinema DSP mode
automatically when surround speakers are unavailable.

Virtual Cinema Front: With Virtual Cinema Front, you
will enjoy virtual 5-channel surround sound with higher quality and
resolution by installing surround speakers at the front. You get more
flexibility to arrange your speakers inside the room, along with easy
enjoyment of high quality surround sound.

Silent Cinema: Silent Cinema makes it possible to hear
large-scale surround sound through ordinary headphones. This is a variation
of Cinema DSP technology that Yamaha developed to let you listen in private
to movies and other multi-channel sources for hours without listening
fatigue.

Cinema DSP Soundfields: Conventional multichannel audio
reproduction systems base their sound on Dolby Digital and DTS decoding, using
matrix and steering technologies to create surround sound effects. Yamaha Cinema
DSP is much more advanced, actually creating richly realized independent
soundfields that envelop you in an unmatched surround sound experience. With
dialog, music and effects ideally located in these separate soundfields, you
will hear sound with accurate placement, smooth movement, exceptional clarity
and richness, and realistic presence. It will seem as if the walls of your room
have disappeared and you are in the middle of your own immense theater. The AV
receiver offers 17 Cinema DSP programs for movies, music, and games.

Note: You can
change the receiver's Cinema DSP effect level (level of the soundfield
effect to be added). You can adjust the level of the soundfield effect
from -6 dB to +3 dB.

CINEMA DSP Parameters: You can adjust the following
parameters of the Cinema DSP modes.

DSP Level: You can change the receiver's CINEMA DSP
effect level (level of the soundfield effect to be added). You can adjust
the level of the soundfield effect from -6 dB to +3 dB.

Delay: Adjusts the delay between the direct sound and
the presence soundfield (1-99ms), surround soundfield (1-49ms), and surround
back soundfield (1-49ms).

Room Size: Adjusts the broadening effect (0.1-2.0) of
the presence soundfield, surround soundfield, and the surround back sound
field.

Liveness: Adjusts the loss (0-10) of the presence
soundfield, surround back soundfield, and surround back soundfield.

Reverb: Adjusts the delay time of the rear reverberant
sound (1.0-5.0s), the delay between the direct sound and rear reverberant
sound (0-250ms), and the volume of the reverberant sound (0-100%).

HiFi Sound Modes: The Yamaha RX-A870 offers two HiFi audio
modes which bypass the receiver's tone & DSP processing for higher sound quality
performance. These HiFi sound modes let you play back input sources without any
soundfield effect processing. When either of these modes are enabled, each
speaker produces its own channel audio signal (without soundfield processing).
When playing back 2-channel sources, such as a CD player, stereo sound is heard
from the front speakers. When playing back multichannel sources, the receiver
produces unprocessed multichannel surround sound.

Straight: 2-channel stereo sources are output from only
the front left and right speakers, while multi-channel sources are decoded
straight into the appropriate channels without any additional tone or DSP
processing.

Pure Direct: Turns off the surround and tone circuitry,
and dims the front-panel display, allowing sources to bypass the decoders
and DSP processors of this unit so you can enjoy pure hi-fi sound from
2-channel or multi-channel sources. During Pure Direct playback no sound is
output from the subwoofer.

Compressed Music Enhancer: Yamaha employs sophisticated
digital signal processing with exclusive algorithms to enable playback that
improves the performance of compressed music formats, including MP3, WMA, AAC, &
Bluetooth (SBC/AAC). The Yamaha receiver's Compressed Music Enhancer feature is even optimized for
Bluetooth wireless audio streaming. With the Compressed Music Enhancer, highs and especially lows are richer
and smoother, bringing music back to life to be as close to the original as
possible.

Dialogue Level & Lift: Dialogue Level Adjustment lets you control
the volume of the vocal sound, so you hear movie dialog and music vocals at the
ideal level for clear, comfortable listening. Dialogue Lift adjust the perceived
height of dialogue sounds. If the dialogue sounds as if it in coming from below
the TV screen, you can raise its perceived height by increasing this setting.

Adaptive DRC: Adaptive DRC automatically adjusts the
dynamic range of the sound according to the volume level. This ensures that
you hear clear dialog, vocals, and all sound effects at comfortable levels.
There is no need to adjust the volume level as you listen; everything from
whispers to big explosions will be heard clearly and comfortably at the same
volume setting. It also tones down loud TV commercials and is ideal for
low-volume, late-night listening when you do not want to disturb others.

Dynamic Range: The amount of dynamic range compression applied
to bitstream signals is adjustable; Min/Auto is suitable for low volume listening,
Standard is typical for home use, and Max doesn't compress the dynamic range at all.

Bass & Treble: You can adjust the balance of the
high-frequency range (Treble) and low-frequency range (Bass) of sounds
output from the receiver' front left and right speakers to obtain a desired
tone. You can independently adjust the bass (50Hz) and treble (20kHz) from
-6dB to +6dB in 0.5 dB increments. The tone control of the speakers or
headphones can be set separately.

Extra Bass: You can select whether to play front
channel low-frequencies through either the front speaker or the
subwoofer, or through both the subwoofer and front speakers. Use the Extra
Bass feature to amplify bass tones, not just in your main room but also on
systems in Zone 2. Even with compact or in-wall speakers which typically
lack bass, you'll hear all your sources with powerful bass sound.

Subwoofer Trim: The Subwoofer Trim control enhances the
low frequencies by avoiding overlap with the front speaker output. This will
result in a cleaner, more focused sound stage while providing a seamless
frequency response. When subwoofer frequency overlap occurs in conventional
systems, the overall sound is "pushed" toward the subwoofer. Subwoofer Trim
takes care of this by separating the low subwoofer frequencies cleanly, thus
stabilizing the front stage while providing a well-balanced enhanced bass
sound.

Zone 2 Volume Equalizer: Automatically adjusts bass and treble
balance to match the volume on systems in Zone 2. Enjoy movies and music
with a natural sound quality balance even at low volumes.

Volume Setup: The Yamaha RX-A870 allows you to customize the
receiver's volume levels.

Volume Scale: You can choose to display the "Relative" volume scale
(-80 to +16dB) or an "Absolute" volume scale (0 to 97).

Max Volume Adjustment: Use this feature to set the
receiver's maximum volume level. This feature is useful to avoid turning the
volume too loud by mistake. You can set the Max Volume from -30dB to +15dB
in 5dB steps, or to +16.5dB (full volume range is -80dB to +16.5 dB).

Initial Volume Setting: Use this feature to set the
volume level when the power is turned on. You can choose between Off (same
as the volume when the unit was turned off), Mute, and -80dB to + 16.5dB
in increments of 0.5dB.

Input Trim: Use this feature to adjust the volume
level of each input. This is useful to balance the level of each input to
avoid sudden changes in volume when switching between input sources. The
range is from -6dB to +6dB in 0.5dB increments.

Audio Outputs: The Yamaha RX-A870 AV receiver is fitted with
binding-post speaker terminals and 7.2ch RCA pre-outs, along with a front-panel
headphone jack.

Speaker Terminals: The receiver has binding post
terminals for all speaker outputs. The binding posts can accept bare wire,
pin connectors, and single banana plugs. These terminals are spaced too far
apart for dual banana plugs and a collar surrounding them prevents the use
of spade connectors. You can select 8 ohms or 6 ohms in the menu depending
on your speaker application. The amplifier supports 4- to 8-ohm Front
speakers, and 6- to 8-ohm Center and Surround speakers.

7.2ch Pre-Out: The AV receiver features 7.2-channel
pre-outs (Front L/R, Center, Surround L/R, Surround Back L/R, and Dual Subs)
for connection to external power amplifiers. The pre-outs are variable. The
dual sub outputs are wired in parallel and output the same signal (they are
not discrete).

Headphone Jack: The Yamaha RX-A870 is equipped with a
front-panel 1/4" headphone jack for connecting a set of headphones, so you
can listen to your music privately. Connecting a set of headphones
automatically mutes the receiver's speaker outputs. Sound effects applied
during playback can also be heard through the headphones.

4K/60Hz: The RX-A870 supports up to 4K (3840x2160
pixels) video
@ 60 frames per second on all of its
HDMI inputs and output. It also supports a 480i, 480p,
720p, 1080i, or 1080p video signal.

HDCP 2.2: Only the receiver's HDMI 1-3 inputs and both
HDMI outputs support HDCP 2.2, which fully complies with the latest
copyright protection standard for 4K video transmission.

4:4:4 Color Subsampling: The receiver also supports RGB, YCbCr
4:4:4, YCbCr 4:2:2, and YCbCr 4:2:0 color subsampling (@ 60Hz or 50Hz). With 4:4:4
color subsampling, luminance (brightness) and chroma (color) are sampled at
the same rate; resulting in an RGB color palette as big as the video
sampling rate for a video image with more colors, plus greater color
accuracy and detail.

Wide Color Gamut (BT.2020): The BT.2020 color standard delivers a
much wider color gamut and represents about 75% of the total visual color
spectrum, while the current Rec. 709 color standard selected as the color
space for HDTVs and early generation 4K Ultra HDTVs covers only 35% of the
total visual color spectrum.

Note: Use a premium high-speed 18Gbps HDMI cable for the best
4K/HDR performance.

HDR 10: HDR 10 is an open standard and currently the
most popular HDR format on the market. It uses static metadata at the start of a movie to tell the receiver
and your TV that the video content is encoded using HDR.

Hybrid-Log Gamma: HLG (Hybrid-Log Gamma) is primarily
designed for live video feed and over-the-air broadcasts. It uses no
pre-encoded metadata and is backwards compatible with SDR. HLG's native
compatibility allows much of today's existing SDR infrastructure to be
re-used for HDR in the future.

Dolby Vision: Unlike HDR 10 which contains static
metadata and HLG which uses no metadata, Dolby Vision uses dynamic metadata
technology which sets individual color and brightness levels for each and
every scene. Dolby works directly with filmmakers at major Hollywood studios
to create superior HDR video masters of blockbuster movies.

4K Video Upscaling: The Yamaha RX-A870 AV receiver will
upscale video signals from analog (480i only)-to-HDMI and HDMI-to-HDMI, up to
4K. This means a much better picture with HDTVs capable of 720p, 1080i, 1080p,
or 4K resolution. Only the receiver's main HDMI output is capable of video
upconversion & upscaling; the sub HDMI output does not support video
upconversion or upscaling.

Dual HDMI Outputs: The receiver's two HDMI outputs are parallel, so
the same HDMI audio/video signal is output through both and can be used
simultaneously (video is output at the resolution supported by both TVs).

ARC (Audio Return Channel): This feature of the
RX-A870's main HDMI monitor output allows audio to be sent from your
compatible HDTV to the receiver through the same HDMI cable already being
used to send audio and video to your HDTV. This eliminates the need for
extra cables connected to your television.

Deep Color & x.v.Color Support: The AV receiver supports Deep
Color and x.v.Color content, which can display a larger color range than
standard-definition schemes. The result is a more lifelike, vibrant picture

LipSync: This function adjusts the delay between audio
and video output. You can do this manually or have the receiver set the
LipSync function automatically. When connected to a TV via HDMI the receiver
automatically adjusts audio output timing (0-500ms) if the TV supports an
automatic LipSync function. You can also manually delay the sound output up
to 500ms to synchronize it with the video image.

Standby Through Mode: When the RX-A870 is in standby
mode (power off), the Standby Through feature allows HDMI source signals to
pass through the receiver to the TV. The HDMI input can be changed using the
remote control. So, there's no need to turn on the AV receiver in order to
switch HDMI sources.

Analog Video Inputs: The RX-A870 AV receiver is outfitted
with one composite video and one component video input. Both the composite and
component video inputs only support 480i. These analog
video inputs are upscaled (up to 4k) and upconverted to HDMI out to your TV (the receiver has
no analog video outputs).

Background Audio/Video: The Background Video feature allows
you to watch a video source while listening to a different audio source. With
the RX-A870, you can select any video input (HDMI or analog) and listen to audio
from any of the receiver's audio sources (including AM/FM tuner, Aux input,
USB, Network, or Bluetooth).

Note: Network setup requires that the receiver be connected
to your TV via HDMI for display of the on-screen menu. The receiver's
network setup cannot be accessed through its front-panel display.

Online Music Services: The Yamaha RX-A870 offers access to
Internet Radio through its built-in Airable by TuneIn; your Spotify Premium account
through Spotify Connect on your Apple iOS or Android device; and your Pandora,
TIDAL, or Deezer

song/artist information from your mobile device.

AM/FM Tuner: The Yamaha RX-A870 AV receiver features a
built-in AM/FM tuner with manual, seek, and preset tuning. The RX-A870 lets you
store up to 40 AM/FM station presets. This can be done manually or automatically
(auto-preset tuning). You can set this receiver to automatically match FM
broadcast frequencies in stereo, or convert the frequency to monaural for weaker
stations. An indoor FM wire antenna and AM loop antenna are included with the
receiver.

Web Control: When connected to your network (with Internet
connection), you can control the Yamaha AV receiver with the web control screen
displayed in your PC's web browser. You'll be able to control functions such as,
Power On/Off & Volume. Internet Explorer 9.x, 10.x, 11.x, or Safari 7.x is
recommended for web browser.

Firmware Updates: New firmware will be released for the
purpose of additional features or product improvements. Firmware updates can be
downloaded from the Yamaha website. If this unit is connected to the Internet,
the receiver will indicate when a new firmware version is available and you can
download the firmware via the network connection. Firmware updates normally take
approximately 20 minutes or longer. Check Yamaha's
Support Download Site for the most recent firmware updates.

AirPlay/Bluetooth/USB Integration

AirPlay: AirPlay lets you stream your favorite songs
directly from your Apple iOS (4.3.3+) device or from your iTunes (10.2.2+)
library on your Windows PC or Mac computer to the AV receiver, over your
home's wireless network connection. From your Apple iOS device you are able
to stream stored music on your device, downloaded music apps, and music on
your iCloud to the AV receiver. From your Windows or Mac you can stream your
stored iTunes music library on your computer to the AV receiver; you can
even download Apple's free
Remote App onto your compatible iOS device to browse and control
playback functions of the music stored in your iTunes music library on
your computer that is being streamed to the AV receiver. With AirPlay you
also get to see song/artist information and album art via the receiver's
on-screen menu (via HDMI).

Built-in Bluetooth: The Yamaha RX-A870 is equipped with built-in
Bluetooth (version 2.1+EDR) for wireless communication between Bluetooth-enabled
audio source devices, headphones, and speakers. The AV receiver can act as a
Bluetooth receiver in order to wirelessly stream music from an audio device, or
a Bluetooth transmitter in order to wirelessly stream music to a set of
BT-enabled headphones/speakers.

Bluetooth Receiver: The RX-A870 incorporates Bluetooth A2DP
& AVRCP, so you can wirelessly stream stored music & music apps from a
Bluetooth-enabled device; like your Apple iPod/iPhone/iPad, Android
smartphone/tablet, Windows Phone/PC, or Mac computer/laptop to the AV
receiver. In addition to support for the standard SBC Bluetooth audio codec,
the receiver offers support of AAC. By supporting AAC, the receiver offers
better audio performance of music streamed from your Apple
iPod/Phone/iPad. Song/artist information will be displayed on your HDMI
connected TV's screen and the front-panel of the receiver. You'll you be
able to control basic playback functions, like Play/Pause & Previous/Next
Track from the receiver's remote; advance music browsing still has to be
done from your Bluetooth source device.

Bluetooth Transmitter: The Yamaha AV receiver can also
act as a Bluetooth transmitter and stream its non-Bluetooth audio sources
(HDMI, Network, USB/iPod, Analog, Optical/Coax Digital, & AM/FM tuner) out
to most any Bluetooth headphone or speaker. You can only pair and stream
audio to one Bluetooth headphone or speaker at a time. You can even have the
same source playing from the main speakers and a Bluetooth speaker/headphone
simultaneously (there is a slight audio delay). Volume control of the
Bluetooth speaker/headphone will be controlled via the Bluetooth device and
not the receiver.

Note: Due to the differences in Bluetooth technology, some
Bluetooth enabled devices may be incompatible, function improperly, or may
not support all features when used with the Yamaha AV receiver.

USB Port: This AV receiver is equipped with a front-panel
USB (type-A) port that allows you to enjoy a variety of music files stored on a
USB mass storage class memory device, such as a USB thumbdrive or portable
digital audio player (not
compatible with USB HDDs). Your USB mass storage class device must be formatted
in FAT 16 or FAT32. You can use the receiver's on-screen menu (via HDMI) and
remote control to navigate your stored music files on your connected USB memory
device. USB portable audio devices that can be charged via USB will be charged
when plugged into the AV receiver's USB port (5V/1A); even in standby mode.
Compatible music files include:

DSD (2.8MHz/5.6MHz)

AIFF/FLAC/WAV (up to 192kHz/24-bit)

ALAC (up to 96kHz/24-bit)

MP3/WMA/AAC (up to 48kHz/320kpbs)

Note: The receiver's USB port does not support Apple
iPod/iPhone/iPad or Android smartphones/tablets.

Multiroom Playback

Zone 2 (Line & Speaker Outputs): The Zone 2 feature allows you to set this receiver
to reproduce separate input sources in the main zone and the second zone (Zone
2). The receiver has dedicated stereo RCA outputs for Zone 2, or the built-in
amplifier can be configured to power speakers in the second zone connected to
the Extra Speaker terminals.

Line-Level Outputs: By using the Zone 2 line-level (RCA) outputs on the AV receiver you can
connect an external receiver or integrated amplifier in a second room, allowing
you to listen to 7.1ch surround in the main room and play a different stereo
audio source in another room of your home. In this setup, the volume of Zone 2
can be controlled by the receiver or an optional integrated amp.

Speaker-Level Outputs: By using the Zone 2
speaker-level outputs on the AV receiver you can directly connect a secondary
pair of speakers in another room of your home, allowing you to listen to 5.1
surround sound in your main room and play a different stereo audio source in the
other room. When the receiver is powering speakers in Zone 2, the surround back
speakers in the main room are turned off (limiting you to 5.1ch in the main
room). In this configuration, the volume of Zone 2 is controlled by the AV
receiver

Zone 2 Sources: Digital (including optical/coaxial) and analog audio sources (including
AM/FM radio); plus Bluetooth, USB, and Network sources can be output to Zone 2.
You can have different sources playing in each zone or have the same source
playing in both zones.

Note: You cannot select different AM/FM radio stations, different
Internet radio stations, or different MusicCast apps for each zone.

Party Mode: The Party Mode allows you to enjoy the AV
receiver's Main Zone audio source in Zone 2, simultaneously (regardless of input
audio signal types - analog, digital or wireless). During the party mode, stereo
playback is automatically selected for all zones. The Main Zone & Zone 2's
volume can be adjusted independently. Utilize this function when you want to
play back an audio source as background music in two rooms of your home.

HDMI Zone B: The receiver's second HDMI monitor output lets
you send the same HDMI audio/video input signal that is being played in the main
zone to a second zone (video is output at the resolution supported by both TVs).

MusicCast Wireless Multiroom Audio Streaming: This AV receiver
supports Yamaha's MusicCast multiroom audio eco-system, which allows you to
wirelessly play back a wide variety of audio sources and content in multiple
rooms of your home (additional MusicCast products sold separately). MusicCast
works with your home's existing WiFi router and Yamaha's free
MusicCast App for
Apple iOS 9.0+ and
Android OS 4.1+. You'll be able to stream the
receiver's tuner, inputs, Bluetooth, and network sources to other MusicCast
products installed in your home. In addition, you'll be able to stream your
MusicCast products' sources to the AV receiver. MusicCast supports the following
source content.

Analog & Digital Sources: The receiver's HDMI,
optical/coaxial digital, and analog input sources can be played
back over the MusicCast eco-system. Multi-channel content (5.1ch/7.1ch) is
down-mixed to 2-channel sound for playback in other rooms without affecting
the master room.

Hi-Res Audio (via USB or DLNA): MusicCast supports Hi-Res audio
via USB or DLNA. The MusicCast system is compatible with Apple Lossless (ALAC)
up to 96kHz/24-bit, as well as FLAC and WAV music files up to 192kHz/24-bit.
It also supports lower resolution music files like MP3, WMA, and AAC up to
48kHz. When multiple MusicCast devices are "linked" for multiroom audio
playback, the Master room device's playback is at the native sampling rate
(up to 192kHz/24-bit), while the other rooms and MusicCast devices
down-converted to 48kHz.

Bluetooth: The receiver's Bluetooth source (SBC codec
only) can be streamed to multiple MusicCast devices, so Bluetooth audio can
be played in multiple rooms simultaneously. The MusicCast enabled receiver can also
stream out non-Bluetooth sources to most any Bluetooth speaker or headphones
(regardless of manufacture), making it convenient to expand MusicCast to
your existing audio products.

Notes:

Up to 10 MusicCast devices can be connected to your home's wireless
network (802.11 b/g/n; 2.4GHz).

If you want to install a MusicCast device to a location that is out
of range of your wireless router, connect another MusicCast device to
the router with a network cable to extend the range ("Extend Mode").

for wireless operation of this receiver and other HDMI-connected sources (via
HDMI CEC). This newly designed remote control features large buttons for
enhanced ease of use.

HDMI-CEC (Consumer Electronics Control): The Yamaha AV
receiver supports HDMI-CEC, which synchronizes the operation of this unit with
other HDMI-CEC devices when connected via HDMI. When the AV receiver is
connected to a HDMI-CEC compatible TV, they will turn ON/OFF together and you
can use the TV remote to control the volume of the receiver. HDMI-CEC also
provides playback functionality with other components, such as your Blu-ray

functions like Play/Pause, Fast Forward/Rewind, Previous/Next Track, or Stop.

Note: Not all HDMI-CEC compatible components and functions
are guaranteed to work.

Remote Connections: The RX-A870 offers a variety of remote
connections for custom integration.

Remote Jacks: The receiver has remote input and remote
output minijack terminals (3.5mm) for use with external IR receivers and
compatible Yamaha components.

12V Trigger Output: The RX-A870 has a programmable minijack
output to send a 12-Volt DC turn-on signal to another component that accepts a
12V trigger, such as a power amplifier or motorized projection screen. The
trigger is programmed either to work with a specific zone (main room or Zone2)
or a specific source.

RS-232C Port: The AV receiver's RS-232C port provides
seamless integration with a wide range of third-party home automation
control systems.

Alexa Compatible (Firmware Update Required): Alexa-enabled
devices (including the
Amazon Echo,
Echo Dot, Tap and
Echo Show) will soon be able to control key functions of a MusicCast system
using voice commands. A firmware update (available early 2018), will be
available for download that allows key functions of MusicCast products to be
controlled using your voice through Alexa-enabled devices (sold separately).

Alexa Skill: The MusicCast skill for Alexa will allow
you to power MusicCast products on and off, control basic playback
functions, make selections from a playlist of favorite music, adjust the

Echo device can be used as a music/audio source for a MusicCast system. All
MusicCast devices offer a Bluetooth input. Just pair your Echo, Echo Dot or
Echo Show with any MusicCast wireless speaker, sound bar or AV receiver and
the sound will play from the MusicCast device. Using the MusicCast app, you
can then select the Bluetooth input and link multiple MusicCast devices for
playback, allowing you to hear it throughout your home. Many MusicCast
products also offer inputs which can be connected to Echo Dot via its line
output, if a wired connection is preferred over Bluetooth. This requires
using an optional analog audio cable (sold separately). Using the MusicCast
app, you can select the wired input and link multiple MusicCast devices for

components and the Alex-enabled devices must be on the same network.

Convenience Features

Advanced On-Screen Menu: The RX-A870 offers an on-screen
(GUI) menu system through its HDMI output. The simple on-screen display combines
text and graphics that make setup and other operations extremely easy. If your
TV is connected to the composite video or component video monitor output, you
will need to use the AV receiver's front-panel display when changing settings.
You can set the receiver's on-screen menu language to English, French, Spanish,
German, Russian, or Chinese. The front-panel
display only offers English.

Note: Initial setup requires that the receiver be connected
to your TV via HDMI for display of the on-screen menu. Many of the
receiver's setup functions can only be found via the on-screen menu and not
the front-panel display.

Scene (for One-Touch Start): The RX-A870 features four Scene buttons on the front-panel
and remote to make operating the receiver easier. Pressing a Scene button will
automatically launch a number of operations that initiate play of the source
controlled by that button; such as powering on the receiver, switching to the
appropriate source input, and recalling the selected DSP surround mode.

Gapless Playback: Many live and classical albums have no
gaps in the music. Gapless playback ensures that there are no pauses between
audio files. This provides playback with no interruptions, the way it was meant
to be heard. Compatible with WAV, FLAC, AIFF, and ALAC music files via USB or
DLNA.

Favorites: You can register up to 40 favorite USB music
files, internet radio stations, and/or other network music content as shortcuts
("Favorites") and access them directly. Only the input source will be registered
for Bluetooth and AirPlay.

Input Rename & Skip: The receiver automatically creates an
input source name that is displayed on the front-panel screen for connected
HDMI-compatible sources. You can also manually rename each input so the display
reflects the actual source. If an input isn't being used, you can hide it from
the display so you don't have to scroll past it when you change sources.

Display Dimmer: You can set the brightness of the front-panel display
from -4 to 0.

ECO Mode: When the ECO Mode is enabled, you can reduce the receiver'
power consumption by keeping the maximum volume, maximum output power, and front
display's brightness low. ECO mode reduces power consumption by approximately
20%.

Timers: The receiver offers a programmable Sleep Timer and
Auto Power Down function.

Sleep Timer: The receiver's Sleep Timer function can be set
turn the unit automatically off after 30, 60, 90, or 120 minutes.

Auto Power Down: If you don't operate the receiver or use the remote
for an extended period of time, the unit will automatically go into standby mode
(Auto Power Down function). The Auto Power Down feature is selectable from 2, 4, 8 or
12 hours. The unit can also be set to power down if it does not detected an
input signal for 20 minutes.

Memory Guard: This feature is used to prevent accidental changes
to the DSP program parameter values and other system settings.

Q & A

Customer Q&A

Crutchfield askedWhy did you buy this?

I researched and compared this unit on Crutchfield Website and felt like I would get the best bang for the buck. I am a big time Apple fan and this unit appears to sync well with my I Phone, I Pad and I Mac.
[ John Jun 06, 2018 ]

I had this brand previously and it performed beyond my expectations
[ KENNY G Apr 19, 2018 ]

I want to upgrade an old Receiver / amplifier to use with TV and WI-Fi and Blue-ray
[ DEAN H Feb 13, 2018 ]

Have a Yamaha receiver that this one is replacing. Getting new receiver with updated features. Yamaha has excellent quality. Information provided by Crutchfield is very valuable in enabling me to make an educated decision on my purchases.
[ Rodger Feb 04, 2018 ]

I have had a Yamaha receiver for ~18 years. It is awesome, but 4 moves across 2 continents takes its toll. Some connections are getting dicey. Still works, good sound through my system, but I want HDMI connections, Bluetooth headphone access and streaming. This unit seems to be a good replacement with the features I was looking for. I hope this one lasts another 18 years.
[ Stephen Jan 14, 2018 ]

I am replacing an old Yamaha receiver to get one that is up to date. The old one is still good otherwise.
[ Ronald Jan 07, 2018 ]

Most inexpensive. In the line with what I needed, pre outs. and it has dolby vision support, and good reviews.
Was going for the Onkyo rz810 but was worried about the hdmi reliabilty and dolby vision support or possible lack of.
Dolby vision on 4k discs is quite amazing
[ Billy Nov 30, 2017 ]

I wanted an A/V receiver that could play audio in two zones, and also wifi for streaming
[ James Oct 24, 2017 ]

My Marantz sr7005 died last night I need a quick replacement... I have had most brands since I was a teenager and I have never had a yamaha..I have known about this company for a long time and I know they are very reputable and I read good reviews about it...so I am giving it a try...my first choice was the denon x6300h or the yamaha rx1070, but i figured to start with this one first...
[ Rey P. Sep 19, 2017 ]

Crutchfield expert recommendation...
[ LaVenus Sep 18, 2017 ]

I use separate amplifiers, so I needed a reciever with multi-channel pre-amp outputs. I selected the least expensive receiver in the AVENTAGE line that included all the features I required. This saved me a good bit of money. The inclusion of 4k and dolby-atmos means I may not have to upgrade again for a long time.
[ Robert Sep 15, 2017 ]

I purchased the Yamaha Aventage RX-A770 for a room that needs only one HDMI output. The unit has worked out great! Excellent sound quality with no boomy sound like competitor models. Video pass-through is excellent and supports the latest 4K standards, including HDR. The model RX-870 is upgrade from the A770, and has two HDMI outputs that will be needed for the room its going. I've tried Denon, Sony and Onkyo new models that came out in May and June. Not as good as Yamaha. I waited for the best!
[ G Jul 06, 2017 ]

Both the 870 & 1070 will support HDR Video including HDR 10, Dolby Vision, and Hybrid Log-Gamma. HDR-10 is supported out of the box and both Dolby Vision & HLG support will be added via a Firmware update. At this time, there is no ETA for the update.
[ Ryan Oct 30, 2017 ] Staff

The best I could offer would be a guess, but I can tell you that I have been completely happy with my A-1070 and wouldn't change a thing. I considered the A-870 before purchasing and feel confident that you can't go wrong with either product. I'm on my third Yamaha receiver over the last thirty years and have never been disappointed.
[ Michael Oct 28, 2017 ]

A "5.1.2 + Bi-amp" configuration would require 9 channels of amplification, while the Yamaha RX-A870 receiver only offers a maximum of 7 at one time.
When using the "Dolby Atmos + Zone 2" configuration and Zone 2 is OFF, all 7 channels from the receiver are directed to the 5.1.2 system. However when Zone 2 is turned ON, power to the Overhead/Dolby Atmos speakers will be cut off and directed to your Zone 2 speakers; limiting you to 5.1 surround in the main room.
For more details or to discuss further, please feel free to contact an Advisor directly by phone (888.955.6000) or online chat. Thanks! My bio: https://www.crutchfield.com/advisors/larry[ Larry Aug 17, 2017 ] Staff

Blaine, While I can appreciate what you would like to do, I personally think it's not worth even trying. My best recommendation is to talk with a Crutchfield technical support person about exactly what it is you would like to try and do-and get that person's opinion.
[ David Jul 18, 2017 ]

The RX-A870 does not allow you to select which channels go out the HDMI port. You can only control if audio us sent out the HDMI port.
[ George Jul 18, 2017 ]

No but I bought the A770 I have a 60" lg I don't know about your vizio speakers the ones in the lg are not very good you will be a lot happier with a good center channel speaker
[ Michael Jul 17, 2017 ]

No they can not.
[ JAMES Jul 17, 2017 ]

I moved from an Onkyo receiver to the Yahama A770 and its been amazing sound quality with no change to my speakers which are Polk center channel and bookshelves that I've had for almost 10 years (from Crutchfields). I don't think you can go with your proposed solution of using your TV speakers; nor, understand why you would want to after making such an investment in your TV. If you think about it, the quality of your TV speaker will come nowhere close to a decent center channel speaker. Furthermore if possible, I suspect you would blow out your TV speakers when watching any decent action movie. My suggestion is to get your bait and rod and go fish. You won't be sorry.
[ Kurt Jul 17, 2017 ]
